Application filed October 16, 1917.

To all whom it may concern:

Be it known that I, ALFRED H. HUM- PHREY, a citizen of the UnitedStates, residing at New York, county of New York, State of New York,have invented certain new and useful Improvements in Gas-Stoves, ofwhich the following is a specification.

This invention relates to improvements in gas stoves. i

The main objects of this invention are: First, to provide an improvedgas stove which is very eflicient in the matter of heat radiation.

Second, to provide an improved gas stove which is well adapted for usein grates or fireplaces.

Third, to provide an improved gas stove in which the parts are so formedand assembled that. the design may be readily changed.

Fourth, to provide an improved gas stove having these advantages whichis comparatively simple and economical in structure.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed .in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a front elevation of a structure embodying the features ofmy invention, a portion of the radiating elements being omitted andthose shown illustrated more or less conventionally, a pair of de- Fig.I.

tached .legs being shown which may be substituted for the attached pair.

Fig. IX is a detail horizontal section on a llne corresponding to line9-9 of Fig. I, lllustrating the manner of attaching the secondpair offront legs shown in Fig. I.

Fig. X is a detail section through the legs of Flg. IX on a linecorresponding to line 10-10 of that figure.

Fig. XI is a detail vertical section on a llne corresponding to line11-11 of Fig. V, showing the method of attaching one of the rear legisi.

Fig. II is a detail vertical section on a l1ne corresponding to line12-12 of Fig. V showin details of the leg attaching means. F 1g. III isa detail plan view partially 1n sectlon, showing the arrangement of thetop bar.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the back wall 1 and side walls 2 are, in thestructure illustrated, formed of sheet metal and in one piece.

The. side walls are provided with outwardly turned flanges 3 at theirfront edges to which are attached uprights 4:. These uprights arepreferably castings and may be ornamented as desired.

The uprights, for the purpose of lightenof Figs. II and III, mounting ofthe suping them, are cored out at 5 on the rear side,

leaving cross pieces 6 at intervals adapted to receive the attachingscrews 7 disposed through the wall flanges. The lower ends of theuprights and the front bar 8 are rigidly secured together by the screws9 and 9. The screws 9 are arranged through the side wall flanges and theuprights to engage the front bar, as shown in Fig. VI. This front barmay also be ornamented as desired and made to harmonize-with theuprights. The rear and side walls are reinforced at their lower ends bythe strap 10. r

' The rear legs 11 have angled seats 12 therein for the rear cornersandare secured by means of the screws 13. Thefront legs 14 are securedto the under sides of the front piece by means of the screws 15. Ifdesired, these legs may be removed and andiron like legs, which areprovided with arms 16, may be attached. The arms 16 are adapted to fitinto the recesses 17 in the en ds of the front bar and secured thereinby means of the screws 18.

The structure is considerably changed in appearance merely by changingthe legs. However, the front bar and the uprights may be changed asdesired.

The uprights are further connected by the top bar 19, which may besuitably ornamented, and the intermediate cross bars 20.

A supporting plate 21 is mounted within the walls, it being secured tothe rear walls by the screws 22 and to the uprights by screws 23. Thisplate has forwardly projecting portion 24 which constitutes a hearth.The front edge of the plate 21 is below the top flange 25 of the frontplate, see Fig. 11. The supporting plate thus serves as a bracing memberfor the walls and uprights as well as to support the parts mountedthereon.

The firebaclr 26 is mounted upon this plate, which has a rib 27 in frontof the fireba-ck. The upper end of the fireback is engaged by theyoke-shaped top member 28, which fits upon the upper edges of the wallsand is secured to the rear walls by thescrews 29 and to the'uprights bythe ears 30,see Fig. VI. This frame member overlaps the fireback-restingupon the top thereof so that the fireback is effectively retained on itsseat on the supporting plate.

The side members of the top bar have downwardly projecting lugs 31 whichengage the front of the firebaclr preventing its tilting forward. I

The supporting plate 21 has a series of burner openings 32 therein.Above these openings I arrange the tubular radiating elements orradiants 33. Y The bottom of these radiants are retained and positionedby the rib 27 and a rib or flange and the lu s 35,see Figs. 11 and V.

The fireback'has a portion 36 at its upper end which overhangs the upperends of the radiants, the overhang being close thereto. This serves todeflect the heat forward'and further adds to the uniformity of theheating of the radiants and in the-general eliiciency of the structure,as is described in my application for Letters Patent, filed May 18,1916, Ser. No. 98337. The upper ends of the radiants are retained by thebail-shaped rod 37 which is pivoted in the end walls so that it maybeswung down in front of the radiantsyas shown in the drawing, or may beswung up to permlt their easy removal 7 orreplacement.

The-burner, designated generally by the numeral 38, is mounted on lugs39 depending from the supporting plate. The burne has ters Patent, is

and at thesame time is comparatively simple and economical in structure;The parts are so assembled that the design may be greatly varied, thatis, a different design of top bar, uprights, front bar, and front legs,may be used with the other parts. This is of very material advantage, asit avoids the necessity for great variety of general structures, and atthe same time it makes it possible to provide changes in design.

The parts are comparatively simple and economical to produce and theymay be very easily assembled.

I have illustrated my improvements in one form in which I have embodiedthe same. I have not attempted to illustrate or describe othermodifications and adaptations, as I believe the disclosure made willenable those skilled in the art to which my invention relates to embodyor adapt the same as may be desired.
